Overview

The packaging envelopes of the modern racing car become tighter each year - leaving less room for auxiliaries such as plumbing. At the same time it becomes more and more difficult to get the cars down to minimum weight. Earl's Ultra-Flex 650™ hose solves these issues. Earl's finest and lightest hose combines a woven Ultra-light Kevlar® braid with a smooth bore PTFE tubing for increased flow and convoluted outside for incredible flexibility. It also has significantly higher flow and pressure ratings than conventional convoluted PTFE hose. Ultra-Flex 650™ is 60% lighter than our stainless braid-protected synthetic rubber hose, and 15% lighter than our Pro-Lite 350™ hose. You have spent a lot of time, energy and money on your race engine and you should bring the life sustaining fluid to it with the best hose on the market today - Earl's Ultra-Flex 650™.
